This invention relates to windrower attach ments and more particularlyto means to prevent grain from the windrower from getting caught in thechains or sprockets of the machine or between the conveyor and roller atthe end thereof, or between the platform and conveyor, or in a corner ofthe machine, etc. A further object is to provide an improved attachmentfor windrowers, which when in use in a field which had previously hadcorn therein prevents the corn stalks from getting caught ybetween theslats of the canvas conveyor thus stopping or impeding the machine.

A further object is to provide means for keeping the moving parts of themachine clear of all material that would clog, impede or stop same inoperation and that may be provided as an attachment for the windrower orbuilt into the Same at the factory.

A still further object is to provide a windrower attachment that is verysimple in construction consisting ordinarily of a single piece ofmaterial, that is positive and efficient in use, inexpensive tomanufacture, and durable.

With the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed, pointed out in the claim and illustrated in the accompanyingdrawings forming part of this patent, and in which- Fig. 1 is a view inperspective of a windrower illustrating the application of the instantattachment.

Fig. 2 is a View in perspective of the attachment per se.

Fig. 3 is a fragmentary plan view of the con* veyor, pitch roller andcertain closely associated d.parts of a Windrower showing the invention,an

Fig. 4 is an enlarged longitudinal vertical cross sectional view throughFig. 3 showing the invention and one method for securing same to theconveyor platform.

Like reference characters denote corresponding parts throughout theseveral views.

The reference numeral I` denotes the windrower having the usual reel 2,canvas conveyor 3, usually an end or pitch roller 4, and platform 5.Extending transversely of said platform and of a length equal to thewidth thereof and secured thereto by suitable fastening means is thebuilt'with or attached device including the flat strip 6 of metal orother material formed with perforations 'I in its ends to permit the useog bolts or the like for securing it in place,

1 Claim. (Cl. 56--192) `platform with the Secured to or integral withsaid strip is the cone-shaped body 8 which extends laterally from onelongitudinal edge thereof, said body portion while substantiallycone-shaped preferably having one rather flat face 9 disposed the planeof said strip, the smaller end of said lbody portion being spacedinwardly from o-ne end of said strip to allow a free strip-edge portionIl), said body extendingapproximately a like distance beyond theopposite end of said strip. I

The attachment is secured to the windrower end Il of the stripsubstantially flush with the forward edge of they platform so that thenarrow end of said body portion-8 isdisposed rearwardly of said edge adistance equal to the extentof the free portion I0, with the large endof said body portion extending rearwardly of said platform and of themachine itself, said strip being secured to the platform contiguous t0the grain opening I2 in the windrower through which it projectsrearwardly, said strip 6 being disposed immediately beyond the pitchroller 4, or beyond the conveyor and platform in the event said roller 4is omitted, with the body 8 spaced therefrom.

Ordinarily grain travelling over the conveyor 3 is pitched by roller 4,or by the conveyor, upon the windrow. The heads of most grains arefluffy and not compact as are the stubble ends, more so when ripe.

I have illustrated a right hand type of windrower. The conventional typeof windrower is driven either by the bull wheel I5 as in the instantcase or by power take-off. The windrower is provided with the said usualgrain opening, with theguide plate I'I preferably of heavy sheet metalthat projects forwardly beyond the cutting bar I8 to encounter thestanding or partly fallen grain and dispose same to the best advantagein the path of said bar; with the draw bar I9, with lever 20 foradjusting the height of the cutting bar above the ground, and with thereel adjusting lever 2l for adjustment of the reel 2.

The bull wheel is provided with a large sprocket that is chain-connectedabout but slightly from the grain opening I2 to the gearing for drivingthe canvas conveyer 3 and pitch roller 4 but this mechanism has not beenillustrated as deemed conventional. Patent No. 2,071,844, February 23,1937, shows an equivalent structure. The grain that is cut or on windrowdoes not cause any trouble by clogging or otherwise at the bull wheelend of the machine. As the grain is cutA it falls upon the conveyer, thebutt ends fall nearest cutter bar I8 and the head ends remote therefromas shown at 22, Fig. 3, the conveyer moving therewith in the directionof the arrow.

As the grain passes from the conveyer the cone 8 guides it away from theroller 4 and from the chains and sprockets of the machine and fromlodgement at the corner formed by the left wall of the grain opening andthe machine frame and falls upon the stubble in windrow. The head endsof the grain are nearest the large portion of the cone 8 and some of thegrain will lie on the windrow as the machine moves forwardly. The grainwill lie on a slight slant or angle to the path of the machine and thisangle will vary somewhat, depending upon thev lengthv and ripeness ofthe grain. Grain lying on a slant to the windrow will pick up betterwith the combine. When the windrow becomes built up with loose and uffygrain some of the grain will ordinarily get caught at this corner orangular point of the machine and a bunch o1' bunches of grain may dragin the windrow until freed from the machine. This corner entanglement ispositively prevented bythe instant attachment whichl serves as a guardagainst obstruction to the moving parts of the machine insuring itsclean operation at all times.

Therefore the head ends will not pitch so far or so readily andsometimes getcaught in the chains or sprocketsof' the machine, orbetween the conveyor and roller, or between the platform and. conveyor.At such times the operator must get down and remove the impacted; grainwhich otherwise would halt the operation of the machine. The grain headsmay contact the free edge I0 of the strip as the machine is in operationand ride along same and be lifted by the cone-shaped body 8, by theouter portion I 3 thereof and nally be deposited from the larger end ofthe cone upon the windrow clear of all parts of the machine, or thegrain will be pitched clear from the cone.

The movement of the machine bringing the grain in contact with theattachment rolls and pushes the heads of the grain over upon thewindrow. The lower end of the cone and the adjacent end of the stripmeet the head ends of the grain first at an angle of approximately tendegrees or the like.

What is claimed is:

In combination with a windrower having a conveyer, a platform and agrain opening; a strip secured to saidv platform and extending beyondthe same and said conveyer, and a tapered body secured to said stripalong its remote lateral edge with its smaller end disposed forwardlyand its larger end rearwardly beyond said strip and the rear end of thewindrower, said body disposed transversely of the width of the windrowerand contiguous toone wall of said grain opening.
